Rijn Muntjewerff started TV DX - as many DXers do - after accidentally discovering distant signals on his domestic TV set. At 28 years of age, Rijn viewed bullfights from TVE chE2 Spain in June 1961. After further DX reception, he installed a roof-mounted mast and achieved some of the first European UHF TV DX.
In the spring of 1970, he erected a 22.5 meter mast for band 3/UHF TV tropospheric reception, and a wideband 40-90 MHz log-periodic array mounted on the roof for Sporadic E, F2, TEP, and Meteor Scatter band 1/2 VHF TV reception.

Due to his exposed location, Rijn has lost several aerials, mainly as a result of the U-bolt/clamp section of diecast housing rotators breaking. To prevent this, Rijn now uses an alignment bearing on top and an internal sleeve pipe inside the mast atop the rotor.

Rijn lives in an area of land about 4.5 meters below sea level called a Polder. This land was reclaimed from the sea. Most of the Netherlands is a flat low land area, used mainly for farming. Due to a flat 7 mile view to the horizon in all directions, Rijn has had great success with distant band 3 and UHF tropospheric TV DX.

Rijn obtained professional help and advice for putting together his DX-TV aerial and equipment system. He uses 9 aerials for DXing work, each aerial has its own masthead preamplifier and own signal feed cable. The two Hirschmann 818 N 60 UHF aerials are connected to a Hirschmann combiner. The coax feed cables are kept separate to
avoid interference from other frequency bands.

In the house, Rijn can connect one of the three UHF cable feeds to his Philips 1970s XT-700 UHF only tuner. He uses a Teling VHF to UHF up-converter. The up-converter UHF output can be connected to the UHF only tuner. One of the five VHF coax cable signal feeds can be connected to the up-converter VHF input. The Philips XT-700 UHF tuner was made in the early 1970s.

For photographing off-screen DX TV, Rijn uses an old Russian made (SMENA) 35mm camera, and Ilford FP4 125ASA film. Rijn does his own Black & White film processing and printing.

Rijn's long-distance television achievements in band 1 have been remarkable, with reception from Australia (ch 0), Korea (AFKN Seoul ch A2), Malaysia (ch E2), Thailand (ch E2), and southern Brazil (Port Allegre ch A2). In total some 2000 TV stations from 68 countries, which is a world record for terrestrial TV DX. Rijn's most distant UHF TV reception has been from SR-2 chE34 Pajala, Sweden.

Since 1962, Rijn has been a member of the Benelux DX club (BDXC). Rijn's Netherlands VHF/UHF antenna system is also the largest TV DX installation in Europe, if not the world. Rijn's impressive DX reception results certainly match the elaborate aerial system.

Rijn moved to a nursing home in 2009, and subsequently passed away in 2014. He was 81.
